IMPROVEMENT IN AIR-CARBuRl-:TING APPARATUS.

Specification forming part of Letters Patent No. 216,879, dated June 24, 1879; application filed April 23, 1879.

To all whom 'it may concern: Y

Be it known that I, RICHARD R. MoFFA'rr, ofthe city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Apparatus for Garbu!V reting Air for Illuminating Purposes, Ste., of which the following is a specication.

The object of this invention is to produce a cheap and simple device for mixing a light hydrocarbon liquid with air, so as to produce a vapor or gas suitable for illuminating purposes, & c.

My invention consists in the combination, in

' a carbureting apparatus, of a stationary outer with a spiral liange, and serving to force air through the disks and saturated material, whereby the desired end is attained.

It also consists in the combination of parts, hereinafterdescribed and claimed.

In the accompanying drawings, Figure l represents a longitudinal central section of my invention. Fig. 2 represents a cross-section of the same, taken on the lineman, Fig. 1. Fig. 3 represents a like view, taken on the line w w', Fig. l.

Similar letters 0f reference in the several figures indicate like or corresponding parts.

A represents a hollow cylinder or case, to the ends of which are fitted end plates, a a', secured in place by screws or otherwise, and provided with legs, where they support the cylinder and its appurtenances. In the upper part of the plates a a are openings for the passage of air, so made that pipes may be applied to them as may be desirable. The cylinder A is separated into two compartments, m m', by a transverse partition, c.

B is a hollow cylinder, mounted on a shaft, d, supported in the end plates, and driven through a cord and weight acting on a pulley, or otherwise, so as to cause said cylinder to rotate within the compartment m of the chamber A. It is provided with one or more spiral flanges, c c, extending around its periphery,

and tting snugly within the inner surface of `its compartment of the cylinder A.

est the partition c are openings to its interior` C. Through the partition c is an air-openin g, i, located in its upper part. n designates pairs of perforated disks, composed in this instance of wire-cloth, secured to the shaft d, so as to rotate through and dip in the gasoline or analogous material in the compartment m of the cylinder A. Between the disks of each pair is placed cotton-.waste"or other similar material. A draw-cock may be placed at the bottom of the duct S, if desired, and gagecocks may be located at the side of the cylinder A, so as to indicate the quantity of liquid within the chambers m and m. In the chamber m is placed water, as represented in the drawings, and within the chamber m is a light hydrocarbon liquid, such as gasoline.

The operation of the invention is as follows: The shaft d, rotating, carries with it the cylinder B and the disks n n, and as the ends of the spiral ilanges c enter the liquid in the compartment m, the air entering the said compart ment is forced forward in the direction indicated by the arrows, (see Fig. 1;) and as one end of the flange does not move out of the liq'uid until the other end has entered it, the air is prevented from moving or passing backward. rlhe water returns through he duct S as fast as displaced, and hence is always in position to immerse the liange and prevent the backward flow of air. The air is forced, through the openin g i in the partition c, into the chamber m, and through the disks n aand the cotton waste, thence out through the opening in the end plate, a', into pipes that convey it to burners. As the 4disks a n are rotated by the shafts d, the cotton-waste or other material between them passes into and out of the liquid in the chamber m, and becomes highly saturated with the liquid, so as to thoroughly imA pregnate with it the air as it is forced through, thus carbureting it fully before it passes from the compartment m. The cylinder B, being hollow and provided with openingsl at the end near the partition e, acts as an air-chamber, in

- which compressed air may be stored up, so as lprinciple of my invention.

Having thus fully described its nature, construction, and operation, what I claim as my invention, and desire to secure by Letters Patent, is-` 1. In a carbureting apparatus, the combination of an outer stationary cylinder or case, perforated disks secured to the central shaft, fitting tightly and rotating Within the outer cylinder or case, for saturating cotton-Waste or other material carried by them with gasoline or other hydrocarbon in said cylinder or case, and'a rotary cylinder provided With a spiral iiange fitting tightly Within said outer cylinder or case, for the purpose of forcing air through the aforesaid disks, substantially as and for the purpose specitied.

2. In a carbureting apparatus, the combination of a cylinder or case divided into two compartments, perforated disks secured to the central shaft, itting tightly androtatingwithin one compartment, to effect the saturation of cotton-waste or similar material carried by them with gasoline or other hydrocarbon, and a rotary cylinder provided with a spiral flange fitting tightly in the other compartment, and serving to force air through the aforesaid disks, substantially as and for .the purpose specied.

3. In a carbureting apparatus, the combination of a cylinder or case composed of two compartments, perforated disks secured to the central shaft, fitting tightly and rotating within one compartment, for saturating cotton- Waste or similar material carried by them With gasoline or other hydrocarbon, a rotary cylin.- der provided with a spiral liange fitting tightly in the other compartment, serving to force air through the said disks, and a duct in the lat-A ter compartment open at all points to the said compartment, substantially as and for the purpose specified.
